Hello House pls i want to ask if anybody knows where i can buy bitcoin cheap and sell at a higher price at the same time or within same day
I think you just monitor in some exchanges like polonie,bittrex hitbtc etc. Prices are almost uniformed with little difference from each exchanges, and looking for cheaper bitcoin is hard to find, and even if you find one, be warned and think first as it might scam or fraud. Better to buy from well known exchange.
